| FrameModuleWhereRowsByC, V, R Method |
Returns a new data frame containing only the rows of the input frame
for which the specified `column` has the specified `value`. The operation
may be implemented via an index for virtualized Deedle frames.
## Parameters
- `frame` - Input data frame to be transformed
- `column` - The name of the column to be matched
- `value` - Required value of the column. Note that the function
is generic and no conversions are performed, so the value has
to match including the actual type.
